I recently did a round-the-state Colorado road trip and can highly recommend it to anybody interested in a huge variety of gobsmacking beautiful scenery. From ancient cliff-fortress ruins in the SouthWest of the state to Rocky Mountain National Park in the North. Great Sand Dunes National Park (shown here in the pictures) is an absolutely amazing place to go. Totally out of the way, but so worth the drive and the amazing hike across the dunes. The experience can be a bit magnified if you come from a coastal area, the air on some of the peaks (like Pike's Peak) is so thin that, until you acclimate, walking more than a little bit results in a queer dizzy feeling that makes the whole experience even more fun. Come prepared though, a pretty large part of the state is so low in population density it's hard to even get mobile phone service. So plan your routes carefully, bring maps and have an independent GPS device that doesn't require data service for route planning.
